My 7 year old granddaughter is stuffy all the time. She's given antihistimine & Flonase every night before bed. I'm concerned about the side effects. She has many many stuffed animals in her room which is so cluttered that I know it is seldom dusted. Could these be the main reason for her problem and the meds are just an easy bandage for the situation. I advised them to clean the room thoroughly and remove the stuffed animals which carry dust mites but of course they think it's cute for her to have and sleep with all these stuffed creatures. They won't listen to me. Please help! Worried!
